R wrapper for 4SAIL model
1 | foursail(refl, tran, rsoil, param)
|
refl |
input leaf reflectance from 400-2500nm (can be measured or modeled) |
tran |
input leaf transmittance from 400-2500nm (can be measured or modeled) |
rsoil |
input soil reflectance spectra from 400-2500nm (can be measured or modeled) |
param |
Vector of SAIL parameter values: * LIDFa: Leaf angle distribution function - parameter a * LIDFb: Leaf angle distribution function - parameter b * TypeLIDF: Leaf angle distribution function type (1 or 2) * LAI: Leaf area index * q: Hot spot effect parameter * tts: Solar zenith angle * tto: Observer zenith angle * psi: Sun-sensor azimuth angle |
Spectra matrix (see spectra()
) (2101 x 4) of reflectance factors
for wavelengths 400 to 2500nm:
* bi-hemispherical reflectance (rddt)
* hemispherical directional (rsdt)
* directional hemispherical (rdot)
* bi-directional (rsot)
